Matching follow-up CE-MRA and IA-DSA were evaluated separately. Evaluation included the presence of aneurysmal remnant, patency and stenosis of parent artery.<\/jats:p>\n                  <jats:p>Twenty-seven patients with 28 aneurysms and 33 matched CE-MRA and IA-DSA studies were evaluated. Nineteen aneurysmal remnants were seen on CE-MRA and 16 on IA-DSA. CE-MRA diagnosed three aneurysmal remnants not appreciated on IA-DSA. Five other remnants were larger on CE-MRA than IA-DSA. None of the remnants were missed on CE-MRA.<\/jats:p>\n                  <jats:p>Parent arteries were patent on both modalities. CE-MRA showed false stenosis of the stented artery in six cases and exaggerated stenosis in two. In 18 cases, CE-MRA showed a short focal \u201cpseudo-stenosis\u201d where the stent's marker bands were located. This was noted whenever the stent's marker bands were located in an artery with luminal diameter \u22642 mm and was called \u201cmarker band effect\u201d.<\/jats:p>\n                  <jats:p>CE-MRA is an accurate technique for follow-up of aneurysms post stent-assisted coiling with excellent depiction of remnants in spite of the presence of a stent. Apparent stenosis of the stented parent artery on CE-MRA is often false or exaggerated. \u201cMarker band effect\u201d should be recognized as an artifact that appears when stent's marker bands are in a small artery.<\/jats:p>","DOI":"10.1177\/159101991201800305","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T05:55:03Z","timestamp":1484114103000},"page":"275-283","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":48,"title":["CE-MRA for Follow-up of Aneurysms Post Stent-Assisted Coiling"],"prefix":"10.1177","volume":"18","author":[{"given":"R.","family":"Agid","sequence":"first","affiliation":[{"name":"Division of Neuroradiology, Toronto Western Hospital; Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Schaaf","sequence":"additional","affiliation":[{"name":"Division of Neuroradiology, Toronto Western Hospital; Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ri.","family":"Farb","sequence":"additional","affiliation":[{"name":"Division of Neuroradiology, Toronto Western Hospital; Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,9,1]]},"reference":[{"key":"bibr1-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)67214-5"},{"key":"bibr2-159101991201800305","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1488"},{"key":"bibr3-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-006-0153-5"},{"key":"bibr4-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.107.508234"},{"key":"bibr5-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.109.553099"},{"key":"bibr6-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1177\/159101991101700106"},{"key":"bibr7-159101991201800305","first-page":"1349","volume":"26","author":"Majoie CB","year":"2005","journal-title":"Am J Neuroradiol"},{"key":"bibr8-159101991201800305","first-page":"1121","volume":"23","author":"Leclerc X","year":"2002","journal-title":"Am J Neuroradiol"},{"key":"bibr9-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-004-2277-5"},{"key":"bibr10-159101991201800305","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1124"},{"key":"bibr11-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1016\/j.neurad.2007.05.002"},{"key":"bibr12-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2272012071"},{"key":"bibr13-159101991201800305","first-page":"1154","volume":"25","author":"Yamada N","year":"2004","journal-title":"Am J Neuroradiol"},{"key":"bibr14-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-005-1375-7"},{"key":"bibr15-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-008-0450-2"},{"key":"bibr16-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.10091528"},{"key":"bibr17-159101991201800305","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1678"},{"key":"bibr18-159101991201800305","first-page":"497","volume":"18","author":"Hartman J","year":"1997","journal-title":"Am J Neuroradiol"},{"key":"bibr19-159101991201800305","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1743"},{"key":"bibr20-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1118\/1.597854"},{"key":"bibr21-159101991201800305","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.10004"}],"container-title":["Interventional Neuroradiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/159101991201800305","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/159101991201800305","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:55:08Z","timestamp":1777460108000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/159101991201800305"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,9]]},"references-count":21,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2012,9]]}},"alternative-id":["10.1177\/159101991201800305"],"URL":"https:\/\/doi.org\/10.1177\/159101991201800305","relation":{},"ISSN":["1591-0199","2385-2011"],"issn-type":[{"value":"1591-0199","type":"print"},{"value":"2385-2011","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,9]]}}}
